GUDGEQN.

Application filed May 9, 1904. $eria1 No. 207,131. (No model.)

To (all whom, it 711,051 concern/.-

Be it known that I, OLE OLSON, a citizen of the United States, residing at Neenah, in the county of Winnebago and State of Wisconsin, have invented a new and useful Improvement in Gudgeons, of which the following is a specification.

My invention relates to gudgeons for insertion into the end of wood rolls and for similar uses; and its object is to provide a device for supporting wood rolls for revolution upon their gudgeons in a firm manner and so that the gudgeons will not be liable to become loose in the rolls, throw them out of a true circle in their revolutions, and thereby make them practically worthless; and it consists of a shaft to be driven centrally into a bore of a suitable size in the end of the roll, leaving its outer end to project for serving as a journal upon which the roll is to be revolved, the shaft being provided at a point much the nearest to the journal end with a hub from which a plurality of arms extend radially, each arm l'laving at its outer extremity a round straight finger arranged parallel with the shaft and of approximately one-half the length of said shaft, each finger being adapted to be driven into the end of the roll through bores of a suitable diameter, the hub and arms being fitted into the end of the roll, so that the shaft, hub, arms, and lingers can be driven into their respective apertures, and thereby hold the gudgeon firmly in position, and as an additional means for holding the central shaft in position a sharp-edged ring is driven into the end of the roll just outside of and in contact with the ends of the aforesaid arms.

My invention is illustrated in the accompanying drawings, in which Figure 1 is a plan of the inner end of the gudgeon. Fig. 2 is a plan of 1ts outer end.

Fig. 3 is a plan of the outer end of a modified form, one having three instead of four arms and fingers. Fig. 4 is a side elevation of the style shown in Figs. 1 and 2. Fig. 5 is an end View of a roll having the style of gudgeon shown in Fig. 2 driven into it and a ring driven in outside of the arms of the gudgeon. Fig. 6 is a side elevation of one end of a wood roll, a part of its end being in section and showing my improved gudgeon in position therein, the front arm being broken off and the ring being shown in section. Figs. 5 and 6 are upon a smaller scale than the previous ones.

Similar numerals indicate like parts in the several views.

1 and 1 indicate the central shafts, Figs. 1 and Lshowing the part of said shafts which is to be driven into the end of roll to be square, while Fig. 6 showsit to be round. If square, the bore for its reception should be somewhat smaller than the diagonal of the shaft, so that its corners will cut grooves along the bore as it is driven, and if round the here should he a very tight lit.

2 and 2 indicate the hubs in the two styles of gudgeon shown, which hubs may be integral with the shaft or separate from it and fitted to the shaft, the latter plan being generally preferable for reasons obvious to a mechanic.

A number of arms 3 and 3' (three arms in very small rolls and four in larger ones will generally be found desirable) extend radially from the hub and are each provided with a round straight linger 4 of about one-half the length of the central shaft, said fingers extending inward. parallel with said shaft for being driven into bores of a suitable diameter in the end of the roll. The hub, arms, and fingers are to be made in one piece. The hub and. arms are to be fitted into suitable seats in the end of the roll, bores of a suitable diameter made for the central shaft and each of the fingers, when the shaft, hub, arms, and fingers may be driven into the end of the roll, the outer end of the hub flush with the end of said roll, after which the ring 5 may may be driven into the end of the roll outside of the ends of the arms. Both ends of a roll being fitted with gudgeons in the abovedescribed manner, the roll-journals may be centered, turned off, and the wood rolls turned off to the desired diameter.

It should be observed that in applying this gudgcon very little wood is cut away, so that the strength of the roll is not impaired, which in rolls of small diameter and great length, such as are largely used in the paper manufacture, is an important feature.

Having described my invention andthe manner of using it, whatI claim, and desire to secure by Letters Patent, is-

1. A gudgeon for wood rolls, comprising a central shaft adapted to be driven into a bore of a suitable diameter in the end of the roll leaving its outer end to project from the end of the roll and serve as a journal therefor, and intermediate the ends of said shaft a hub having a plurality of arms which extend radially from said shaft at right angles therewith, the outer end of each arm being provided with a round straight finger which extends inward parallel with the aforesaid central shaft, both the fingers and arms being adapted to be driven into apertures in the end of the roll of a suitable size, said arms flush with the end of the roll, substantially as described.

2. A gudgeon for wood rolls, comprising a central shaft adapted to be driven into a bore of a suitable size in the end of a roll, leaving its outer end to project a much less distance than its inner end enters, and to serve as a journal upon which the roll may be supported for revolution, a hub arranged intermediate the ends of said shaft, a plurality of arms extending radially from said hub, said hub and arms being adapted to be seated in the end of the roll, flush with its outer end, each arm having arranged at its outer end, parallel with said shaft, a round, straight finger of approximately one-half the length of said shaft which is adapted to be driven into a bore of a suitable size in the end of the roll, and in combination with said gudgeon aring adapted to be driven into the end of the roll, outside of, and in contact With the outer ends of said arms, substantially as set forth.

3. A gudgeon for wood rolls, comprising a central shaft adapted to be driven into a bore of a suitable diameter in the end of the roll leaving its outer end to project from the end of the roll and serve as a journal therefor, and intermediate the ends of said shaft, a hub having a plurality of arms which extend radially from said shaft at right angles therewith, the outer end of each arm being provided with a round, straight finger, which extends inward parallel with the aforesaid central shaft, both the fingers and arms being adapted to be driven into apertures in the end of the roll of a suitable size, said arms flush with the end of the roll,and in combination with said gudgeon, a ring adapted to be driven into the end of the roll, outside of, and in contact with the outer ends of said arms, substantially as set forth and shown.

OLE OLSON.
